Claims priority, application Great Britain November 7, 1953 8 Claims. (Cl. 12--1) This invention is concerned with improvements in machines suitable for use in performing lasting or analogous operations on` shoes, such operations involving the tensioning of stock either about a last or a shoe bottom member to cause the stock to lie snugly against the last or such shoe bottom member. Examples of such operations are those involving the tensioning of an upper about a last or the tensioning of a platform cover about a platform providing a bottom member for a shoe. The term shoe is used herein generically as indicating outer footwear generally and includes the article in an uncompleted state.

There will be hereinafter described a particular construction of machine, provided by the invention and illustrative thereof, the illustrative machine being a machine suitable for use in performing lasting or analogous operations on shoes in which different portions of the stock are tensioned, successively, in differentlocations along the marginal edge of the bottom of a shoe by means ofa rapidly reciprocating gripper and in which what may be termed the lasting margin of the tensioned stock is thereafter, by an overlaying member with which the machine is provided, laid inwardly across and pressed against a bottom member of the shoe so as to be secured in so-called lasted position thereon by means of an adhesive which has previously been applied to the inside surface of the lasting margin of the stock and/or the adjacent marginal portion of the shoe bottom member.

One example of a machine suitable for use in performing lasting or analogous operations onV shoes is disclosed in United States Letters Patent No. 2,595,323, issued on May 6, 1952, in the names of Charles M. Bagshaw and Harold Lane, which machine comprises a holddown member for engaging the bottom of a shoe adjacent to the marginal edge thereof, a gripper device for seizing the lasting margin of the stock to be tensioned and for pulling the stock inwardly over the bottom of the shoe (the gripper device having a component of movement in a direction extending heightwise of the shoe away from the shoe bottom during an early portion of its movementinwardly of the edge of the shoe bottom and a component of movement toward the shoe bottom during a later portion of its inward movement to lay the lasting margin against the shoe bottom member), a presser feed foot, arranged to be operated in time relation to the gripper device, for pressing the lasting margin against the shoe bottom member and for exerting a feeding action on the work, and a feed retaining member, movable heightwise toward and away from the shoe bottom intime relation to the operation of the presser feed foot, to restrain the shoe against retrograde movement during the return back-feeding movements ofthe presser feed foot. The presser feed foot is movable successively in a direction heightwise of the shoe toward the shoe bottom and into pressing engagement with the; lasting margin, in a direction. in which the shoe is fed through the machine, in a direction. extending heightwise of. the shoe away from the shoe bottom, and in a direction reverse to that in which nited States Patent ice the shoe is fed through the machine. The machine disclosed in said patent is arranged to operate at a relatively high speed and while it is capable of operating satisfactorily the rapidly operating shoe bottom engaging instrumentalities, particularly the presser feed foot and the feed retaining member, may tend to set up vibrations which cause discomfort and fatigue to an operator of the machine. Moreover, the action of the presser feed foot may not always be as positive in its work feeding action as is desired and consequently substantial care and effort on the part of the operator is necessary to ensure the smooth and even passage of the work past the gripper device.

An object of the invention is to provide an improved machine suitable for use in performing lasting or analogous operations on shoes which will be simpler in construction and which will be more effective and smoother in operation as compared with the machine disclosed in the patent above referred to.

With the above objects' particularly in view, the illustrative machine hereinafter described is provided with a gripper device which not only' has components of movement inwardly of the edge of the shoe bottom while moving heightwise of the shoe iirst away from the shoe bottom and then toward the shoe bottom (the return movement of the gripper, after it has released the lasting margin, being effected substantially parallel to the shoe bottom) but, in order to exert a feeding action on the shoe, has a component of movement in the direction in which a shoe is fed through the machine. In the illustrative machine hereinafter described there is no presser foot or feed retaining member, as in the machine disclosed in the patent above referred to, but the overlaying device of the said illustrative machine comprises a continuously rotating wiping disk yieldingly urged into engagement with the lasting margin after it has been laid over the shoe bottom member by the gripper device, the disk being arranged to wipe the margin inwardly from the edge of the shoe bottom and the periphery of the disk being provided with a. number of helically disposed ribs the lead of which is such that the ribs as they rotate have a component of actiony in the direction of feed of the shoe. The feeding movement of thegripper device extends obl'iquely toward the wiping disk and is timed. to occur as the gripper is moving toward the shoe bottom to lay the margin of the tensioned stock thereagainst, so that, at the end of the feeding movement, the gripper device lies closely adjacentV to one side of the rotating wiping disk and therefore acts to present the portion of the lasting margin engaged by the gripper device in position to be wiped down by the wiping disk, the grooves in the periphery of which assist in the dispersal or distribution of small pleats formed in the lasting margin as it is laid over the shoe bottom member around curved portions thereof (for example, around the toe end of the shoe).

The illustrati-ve machine, furthermore, has a holddown member which engages-the shoe bottom member and with the wiping disk holds the shoe against heightwise movement resulting from the pull of the gripper, and with an edge gage for assisting in positioning the edge of the shoe bottom in correct relation to the gripper device.

Inaccordance with another feature of the invention, the holddown member is mounted for floating movement inV opposite directions extending heightwise of the shoe and means are provided for limiting the extent of movement of the holddown member in either direction, said movement limiting means' being so arranged that movement of the holddown member away from the shoe bottom` is limited to a position in which a foot thereof is substantially in the plane of operation of the wiping disk.

In order that the above and other of the various objects and fea-tures of ythe invention may be more clearly understood, there will now be given, with reference to the accompanying drawings, amore detailed description of the illustrative machine aforesaid. It is to be clearly understood, however, that the illustrative machine is selected for description merely by way of exemplication of the invention and not by way of limitation thereof.

In the drawings,

Fig. l shows the illustrative machine as seen from the right-hand side, portions of the frame being broken away and some parts being shown in section;

Fig. 2 comprises diagrams showing the paths of movement of certain parts of the machine;

Fig. 3 is a view in front elevation of a clutch mechanism associated with the machine; and

Fig. 4 is a View on an enlarged scale of certain of the operating elements of the machine. Y

The illustrative machine comprises a hollow casting 2 mounted on a column of suitable height (not shown) and provided with a cover 4 in which casting mechanism for operating the gripper is housed. The casting 2 also provides an oil reservoir for lubricating the mechanism.

For positioning the bottom of a shoe to be operated upon heightwise with respect to the gripper, the illustrative machine is provided with a holddown foot 102 mounted in the machine as hereinafter described, while, for determining the position of the edge of the shoe in a direction extending forwardly and rearwardly of the machine, with respect to the operating point of the gripper, there is provided an edge gage 104 formed on a bracket 106 secured to the front of the casting 2. The gripper is arranged to seize the lasting margin of the stock, for eX- lample of a platform cover C, at a locality adjacent the edge of the shoe bottom member, for example a platform or heel member H (Fig. 4), and to move inwardly of the edge of the shoe bottom member and while so a link 46 is received. A ball-ended lower end portion of the link 46 is received in a socket provided in an arm 48 of a two-

armed lever

48, 50 pivoted on a cross shaft 52 carried by the casting 2. The arm 50 is pivotally connected to one end portionof a link 54, the other end portion of which is pivotally'connected to the pin 28. The pin 28 is also connected to a forward end portion of an arm 56 projecting from the sheave of an eccentric 58 keyed to the shaft 42. The eccentric 58, on-rotation of the shaft 42, imparts fore and aft movements to the supporting member 18 for the gripper while the cam 40 raises and lowers the link 30 in time relation to the fore and aft movements of the supponting member, causing this doing to move somewhat upwardly away from the shoe bottom member and then, during the final stage of the inward movement of the gripper, to move down toward the shoe bottom member to lay the margin of the tensioned stock against that member. Furthermore, as will be described hereinafter, during the downward movement of the gripper it is moved in a transverse direction to exert a feeding action on the work and to present the margin of the tensioned portion of the stock to an overlaying device comprising a continuously rotating wiper disk 108 having a number of spirally arranged ribs 110 in its periphery.

The gripper comprises a front jaw 8 and a rear jaw 10. The front jaw 8 is lixedly secured to a forward end portion of a rod 12 slidable endwise in a sleevelike portion 14 of a carrier 16 to which the rear jaw 10 is secured. The rod 12 has a square-sectioned portion 17 which cooperates with a ilat on the carrier 16 to restrain the rod against turning in the sleeve-like portion 14 of the carrier. The sleeve-like portion 14 of the carrier 16 is journaled in a tubular portion of a grippersupporting member 18 to which is secured a rearwardly and downwardly extending arm 22.

The member 18 is pivoted, by means of a pin 20, on an upper end portion of a rocker arm 24, this arm being pivoted on a shaft 26 carried by the casting 2. The arm 22 is pivoted, by means of a pin 28, on an upper end portion of a link 30, a lower end portion of which is pivoted, by means of a stud 32, on an arm 34, of a twoarmed lever 34, 36. The lever 34, 36 is fulcrumed on a shaft 38 carried by the casting 2 and the arm 36 carries a cam roll 39 riding in a cam track (not shown) formed in a cam 40 xed to a shaft 42 journaled in bearings in the casting 2.

The sleeve-like portion 14 of the carrier 16 projects beyond the rear end of the tubular portion of the supportin a socket in which the ball-ended upper end portion of ing member 18 and has xedly secured to it an arm 44` member =to rock about the pin 20 and thereby imparting to the gripper heightwise movements. The cam track of the cam 40 is so shapedthat the pin 28 is caused, as a result of the combined action of the cam and the eccentric 58, to trace out a path substantially of the form ABCA, shown in chain lines in Fig. 2, as a result of which the gripper jaw 10 traces out a path substantially of the form abca, shown in chain lines in Fig. 2, providing the inward and heightwise tensioning movements of the gripper above referred to.

The front gripper jaw is urged yieldingly rearward toward the rear gripper jaw by means of a tension spring 60 connected between an anchorage 62 secured to the rod 12 and spring tension adjusting means hereinafter described. For controlling opening and closing movements of the front gripper jaw, the illustrative machine is provided with an abutment screw 64 threaded transversely through a boss at an upper end portion of an arm 66. The arm is pivoted at its lower end on a pin 68 carried by a bracket 70 bolted to an upstanding portion 72kof the casting 2. Pivotally connected to the upper end portion of the arm 66 is a forward end portion of a link 74, a rearward end portion of which is pivotally connected by means of a stud 76 to an arm 78 formed on a sheave 80 of an eccentric 82 keyed to the shaft 42. The sheave 80 has integrally formed therewith another arm 84 pivotally connected by studs 86, 88 and a link to an arm 92 formed on a sheave 94 of another eccentric 96. The eccentric 96 is keyed to the shaft-42. Also pivoted on the stud 88 is one end portion of a link 98, the other end portion of which is pivoted on a cross shaft 100 carried by ythe casting 2. The eccentrics 82, 96 and the parts associated therewith are so arranged that the pin 76 is caused to trace out a path substantially as indicated by the chain line PQRSP in Fig. 2.

. The arrangement of the gripper operating mechanisms is such that when the rear gripper is at the point a the stud 76 is at the point P. During an early portion of the advancing movement of the rear jaw the stud 76 moves to the point Q allowing the front jaw to move rearward under the action of the spring 60 to grip the work against -the rear jaw. With the work gripped, the rear jaw, and with it the front jaw, moves forward and upward (a-b, Fig. 2) and then downward (b-c, Fig. 2) to tension the stock and lay it over the shoe bottom member. By the time the rear jaw has fully advanced to the point c the stud 76 has reached the point R and, while the rear jaw retreats (in a horizontal plane), the stud 76 traces out the path R-S during which the set screw 64 engages the rod 12 and holds the front jaw in a forward position so that the jaws open to release the stock, after which the front jaw moves rearward somewhat toward the rear jaw so that when the rear jaw is fully retracted the front jaw occupies a position determined by the positioning of the stud 76 at the point P. The cycle is then repeated.

The work-feeding movement of the gripper is obtained as aV result of rocking the carrier 16 about the axis of the tubular portion of the supporting member 18, it being Iappreciated that the work-gripping portions of the jaws 8 and 10 liesome/distance below that axis. The timing of the. work-feeding movements is such that, as the gripper is lowered from the point bw(Fig. 2,)l to the point c, the carrier 16 is rocked clockwise (as seen from the fron-t of the machine) about the said. axis to cause the-gripper jaws to approach the side ofthe disk wiper 108. After the grip on the margin has been releasedand. the rear jaw moves to its rearward position, the carrier 16 is swung anticlockwise to eiect the back-feeding movement of the gripper, the shoe being held against retrograde movement as a result of the frictional drag imparted to the laid down margin by the periphery of the disk 108, the direction of rotation of which and the arrangement of the grooves on its periphery being such as to wipe the margin 'inwardly of the edge of the shoe bottom member while a component of force is also applied to the margin in the direction of work feed.

The disk 108 is secured to a transverse shaft 112` journaled in an arm 114 pivotally mounted on. a. sleeve 116 carried by a bracket 115 secured to the cover 4. The axis of the sleeve extends widthwise of the machine. The arm 114 is urged downward by a relatively strong'tension spring 118 connected between the arm 114 and a hook on the casting 2. Downward movement of the. disk is limited. by engagement of a set screw 117 inthe arm 114 and aat on the casting 2. The shaft 112 haskeyed thereto a pulley 152 driven, through a belt 154, from a pulley 156 keyed to a countershaft 151 driven byy a belt 153" and a pulley 158 from a second countershaft 159 journaled in bearings ina bracket 161 secured to the. cover 4. The countershaft 151 is journaled in the sleeve 116 about which the arm 114 carrying the disk 108 is fulcrumed. The tension in the belt 154 is controlled by-an idle pulley 190 eccentrically mounted on a studV 192 secured in the arm 114.

The means for adjusting the tension of the gripperclosing spring 60 comprises an arm 1Z0 which carries a pin 121 to which the rear end' of the spring is connected. The arm 120 is secured to a cross shaft 122 journaledin a bearing in the casting 2. The cross shaft 1'22 hassecured thereto a second arm 124 which lies immediately in front of the arm 120, las seen in Fig. 1, andy carries a stud on which a rearward end portion of a link 128A is carried. A forward end portion of this link is pivotally connected to an arm 130 of a two-armed lever 130, 132. Thelever 130, 132 is mounted on a hub of a second

lever having arms

134, 136 and the angular relationship of the lever 130, 132 relatively to the arms 134', 136 may be adjustably set by means of apin-138ca1ried by the arm 132 and received in one of a plurality of holes 140- in the arm 136. The arm 134 haspivotall-y conneeted thereto a forward end portion of a link 142, a rearward end portion of whichy is provided with a slot 144 through which extends the pin 121, theV pin 121 thus sup'- porting the rear end portion of the link 142. The link 142 has a downwardly extending abutment 146 secured to it near its forward end and this labutment lies behind the anchorage 62 on the rod 12. The arm- 134 also has pivot-ed to it a rearward end portion of a. link 148, the forward end portion of which is pivotally connected with an arm supporting the holddown foot 102.

The countershaft 159 journaled in. the bracket secured to the cover 4 is continuously driven through a belt drive from a pulley (not shown) secured to the armature shaft of an electric motor (not shown) mounted on the machine frame. rThe countershaft 159, lastreferred to, also drives, through another belt 163, a driving member 170 of a disk type clutch 171 through which the shaft 42 may be driven on depression of a treadle (not shown) pivotally mounted in the base of the column.. The. member 170 is journaled on a bushing;173th1eadedonthe end of the shaft 42 (Fig. 3), while the clucth 171 is. keyed to this shaft. Journaled on an extension of shaft 38 is a bellcrank lever having two

arms

175, 177. The arm-` 177 carries at its outer end a cam` plate 179- adapted to. engage a thrust ball 17.2 mounted in. the outer end of a hub. on the driving member 170. The driving member 170 is conposition,V

stantly` urged to the right (Fig. `3) by means of ay com'- pression' spring 176. Mounted on the arm 175 is a pin 178 towhich thereis connected by means of a compression` spring 181 and collars 183, 185 a downwardly extending link 187.

The holddown foot 102 is formed at the base of a stem 184 slidably -received in a block 186 secured to an arm 188 by screws 189 extending through slots in the block, the block thus being adjustable heightwise with respect to the arm 188. A relatively light compression spring 191 is received in the block 186 between a shoulder on `the stem and a shoulderV formed by areduced upper end portion of the bore in which the stem 184 slides. Nuts 194 threaded on a portion of the stem 184 extending upwardly beyond the block 186 determine the amount of yielding movement of the stem 184 relatively to the block 186. Upward, movement of the foot -is limited by engagement of a shoulder 193 on the stem 184 (Fig. 4) with the under side of the block. The purpose of providing the yield between the foot and the block will be hereinafter referred to. Should: no capacity for such yield be required, the nuts 194 may be so adjusted that the shoulder 193 on the stem 184 is clamped against the under side of the block 186. In Fig. 1 the foot 182 is shown in its raised i. e., the position it occupies when a shoe bottom is thrust upwardly against it, although for the sake of clarity'` no shoe is` shown in that figure.

The a-rm 188. is fulcrumed on a cross shaft 196 carried in the cover 4 and there is an arm 198 formed integrally with the arm 188. The arm 198 is connected by means of a link 200and pivot studs 202, 204 with an arm 206 pinned to a cross shaft 208 journaled in the cover 4.` The cross. shaft 208.is connected to the treadle above referred tothrough an arm 289 fixed on the shaft, a 210, an arm. 212 secu-red to a cross shaft (not shown) journaled'. in the` column, and a link between the treadle and. a second arm secured to that cross shaft. The arm just-.referred to also hasV connected to it the link 187 for operating the clutch.

When the treadle above referred to is held in a raised positionby a spring (not shown) the arm 188 carrying the holddown foot 102 is held in a position in which i-t` is inclined forwardly and upwardly (the holddown foot then being in an inoperative position); the front jaw of the gripper is heldin a forward position, through the action ofthe link 148, arm 134, link 142, causing the abutment 146 to engage the anchorage 62 on the rear end of the rod 12; the arm 120 is swung forward through the section of the lever 130, 132 (connected to the lever 1-34, 136), link 128, arm 124 and cross shaft 122 to.v prevent they spring 60 being unduly tensioned for the. time the machine is idle; and the clutch is held disengaged by spring 176.

The fact that the gripper jaws are stationary and open while the holddown foot is in an out-of-the-way position facilitatesy the introduction of work to the machine. On depressionl of the treadle the holddown foot is swung downward and rearward to its operative position (determined by engagement of a lug on the arm 209 with a stoppin 220. in. the cover 4); the front jaw of the gripper is released to the action of the spring 60; the arm 120' is swung` rearward to a position determined by the setting of the spring tension adjusting means 132, 136; and the. clutch for the gripper-operating mechanism is engaged.

rlhe'feeding of the work by the gripper acting on the platform cover and presenting it to the continuously rotating disk wiper, by a movement obliquely toward the. wiping disk and downward toward the bottom ofthe shoe, results not only in a smooth feedingaction but the margin is'laid down smoothly, any fullness in the material` being taken up in small relatively uniformly distributed pleats` The production of a dat margin- Witha well` defined feather edge is thus facilitated. The. fact. that,` when the treadle is` released at the end of an 7 V operation on a shoe, the disk wiper remains rotating after the gripper has ceased to function enables the operator in removing the shoe from the machine to wlpe down the last little pocket in the lasting margin left by the retreating gripper.

Normally, the shoe bottom engaging foot 102 is held in its most elevated position by the pressure of the shoe bottom thereagainst and substantially in the plane of operation of the wiping disk 108, see broken line position in Fig. 4 in which the line X--X indicates the plane of operation of the wiping disk. In operating on shoes having scooped heels the spring associated with the holddown foot causes the foot to follow down the contour of the shoe bottom, see solid line position in Fig. 4, as the region of operation proceeds from the relatively flat heel part in the heel, thus helping to ensure that the foot does not ride over the lasting margin in this region.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
